Hallo Jim, > On powerup, an onboard uC will .... If you allow me to add an idea: why not monitoring the RESET line? Otherwise I have to power-cycle the C= every time I want to change the image. A reset is more friendly for the electronics. > I have two goals. A Software ROM that can be loaded with kernals > of your choice, With all respect, what is the added value for the average user? How many kernals will someone use? I myself use three, which fit in one 27256. A 27512 can contain up to eight. A small trick allows you to use a 27256/27512 in a C128 having 3/7 kernals at your disposal. Only some dipswitches are needed to choose the wanted Kernal. For developers it certainly has a value: the device can be used to develop new kernals, games or whatever. But then IMHO a SD-card should be used; extracting and refitting a FlashROM every time has it risks. (FYI: I put a textool socket in my 1541 to be able to test new kernals for the harddisk project) > and a cart ROM emulator, Here I agree, providing that you use a SD-card. IMHO a FlashROM cannot contain all existing games/tools. I have no idea if they would fit on a SD-card but exchanging a SD-card is done much quicker and safer! Yet another thing to think about: some cartridges use I/O for disabling itself on command, changing the EPROM etc. If VICE can handle this using CRT files, what about your device? If you allow me to add another idea: what about adding a kind of communication port, like USB or RS-232? In this way you can upload the needed software into your RAM/FlashROM using a PC or other device. Having developing in my mind, it is even quicker then exchanging SD-cards IMHO. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
